Be warned you need to interpret the codes from your old bulbs and find an exact match for voltage, connector type and physical size. ### ⭐⭐⭐⭐⭐ Five Stars *by D***R on Reviewed in the United States on 28 July 2018* Light bulb things work properly. ### ⭐ Early Death *by J***. on Reviewed in the United States on 22 August 2021* The bathroom vent has two of these bulbs in it. I have an old habit of writing the date on the tube when it is put into service. When these were plugged in they were dated. 2/25/21. They both died the same day 8/22/21. They were on when we showered and when the air was stale from throne work. Given a kind 3 hours per day that is 531 hours. The package says it can last up to 20,000 hours but the bulbs fail before 600 hours. ## Frequently Bought Together - Sylvania (10 Pack) 20672 CF18DD/E/835/ECO 18-Watt 3500K 4-Pin Double Tube Compact Fluorescent Lamp, 10 Count (Pack of 1), White - Sylvania S6739 (10 Pack) 20673 CF26DD/E/835/ECO 26-Watt 3500K 4-Pin Double Tube Compact Fluorescent Lamp, 10 Count (Pack of 1) - (25 Pack) Sylvania 20673 CF26DD/E/835/ECO 26-Watt 3500K 4-Pin Double Tube Compact Fluorescent Lamp --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/327695697-10-pack-20672-cf18dd-e-835-eco-18-watt-3500k](https://www.desertcart.vn/products/327695697-10-pack-20672-cf18dd-e-835-eco-18-watt-3500k) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-23*
